Abstract For solving the problems of high breakdown voltage and power-flow current in the gas discharge tube applied in lightning protection, a multi-gap model for gas discharge was constructed based on Townsend theory and Parson's law. Moreover, the breakdown voltage of the proposed model is β (β<1) times the breakdown voltage of the ordinary single gas discharge tube. The lighting current impacting experiment was carried on the multi-gap discharge tube. The conclusions can be drawn as follows. The breakdown voltage of the proposed model is 5 times less than that of the traditional gas discharge tube, and the response time can be shorten to 200ns. Furthermore, the rising rate of residual voltage can be reduced to 0.3kV·μs^-1. Besides, the multi-gap gas discharge model can reduce or even remove the power-flow current within a certain range of lightning current.

Key words： Multi-gap for gas discharge breakdown voltage lightning current response time delay rising rate of residual voltage power-flow current
